Hey Thomas, to access (and therefore read or modify) the value of an object property, you do this: 

object.propertyName

So if you want to change the age property of addy, you would do this: 

addy.age = 4;

And it's as simple as that! You can also access an object property's value with bracket notation: 

addy['age'] = 4;

I hope this helps!

So why isn't the following also the correct answer as taught in the lesson? When run in the console it gives the answer of 4.

const addy = { animal: 'dog', age: 3, breed: 'pug' }; const message = Addys age is ${addy.age +1}.; console.log(message);
